(3) Related Functions on Advanced Autotuning by Reference
This section describes functions related to advanced autotuning by reference.
Notch Filter
Usually, set this function to Auto Setting. (The notch filter is factory-set to Auto Setting.)
If this function is set to Auto Setting, vibration will be detected automatically during advanced autotuning by
reference, and the notch filter will be set.
Set this function to Not Auto Setting only if you do not change the notch filter setting before executing
advanced autotuning by reference.
Anti-Resonance Control Adjustment
This function reduces low vibration frequency, which the notch filter does not detect.
Usually, set this function to Auto Setting. (The anti-resonance control is factory-set to Auto Setting.)
When this function is set to Auto Setting, vibration will be automatically detected during advanced autotuning
by reference and anti-resonance control will be automatically adjusted and set.
Probable Cause Corrective Actions
The main circuit power supply was OFF. Turn ON the main circuit power supply.
An alarm or warning occurred. Remove the cause of the alarm or the warning.
Overtraveling occurred. Remove the cause of the overtravel.
Gain setting 2 was selected by gain switching. Disable the automatic gain switching.
Error Probable Cause Corrective Actions
The gain adjustment
was not successfully
completed.
Machine vibration is occurring or the posi-
tioning completed signal (/COIN) is turning
ON and OFF when the servomotor is
stopped.
• Increase the set value for Pn522.
• Change the mode from 2 to 3.
• If machine vibration occurs, suppress the
vibration with the anti-resonance control
adjustment function and the vibration sup-
pression function.
The positioning
completed signal
(/COIN) did not turn ON
within approximately 10
seconds after
positioning adjustment
was completed.
The positioning completed width is too nar-
row or proportional control (P control) is
being used. • Increase the set value for Pn522.
• Set 0 to V_PPI in the servo command out-
put signals (SVCMD_IO).
